Working in forced postures and standing continuously can be classified as straining the musculoskeletal system.
Since such postures are frequently used in hospital canteen kitchens, we used kinematic analysis to determine the working postures of canteen kitchen staff.
In this study, the daily work routine of 18 (11 w/7 m) workers of a hospital canteen kitchen (Frankfurt Main/Germany) aged 21-62 years (46±13 years) was examined by means of kinematic analysis (CULEA system; IFA; Sankt Augustin/Germany) and a detailed computerized analysis of the activities performed on-site. Angle values of the head and trunk were evaluated in accordance with ergonomic standards and presented using percentile values (P05-P95). The OWAS method was also employed to capture the proportions of standing, walking and sitting work.
The kinematic posture analysis showed for all activities on the conveyor belt a tendency towards a dorsally inclined body position: trunk inclination (-7.5° to 0), thoracic spine inclination or a bending forward (-11.3° to 0°) and curvature of the back within the thoracic spine (-15.2° to 0°). In addition, >90% of the "activities on the belt" (46% of the daily working routine) were carried out standing.
The activities on the conveyor belt were characterized by a tendency towards hyperextension of the trunk, possibly due to a too high working environment. Furthermore, an increased burden on body structures while standing can be concluded. From a primary prevention perspective, this increased standing load should be reduced by behavioral and relational prevention measures.
在强制姿势和连续站立中工作可归类为对肌肉骨骼系统的紧张。
由于此类姿势经常在医院食堂厨房中使用，我们使用运动学分析来确定食堂厨房工作人员的工作姿势。
在这项研究中，通过运动学分析（CULEA 系统；IFA；德国圣奥古斯丁）和对现场活动的详细计算机化分析，对 18 名（11 名女性/7 名男性）年龄在 21-62 岁（46±13 岁）的医院食堂厨房工作人员的日常工作进行了检查。头部和躯干的角度值根据人体工程学标准进行评估，并以百分位数值（P05-P95）表示。OWAS 方法还用于捕获站立、行走和坐姿工作的比例。
运动学姿势分析显示，在输送带上的所有活动中，身体都倾向于向后倾斜：躯干倾斜（-7.5°至 0°），胸椎倾斜或向前弯曲（-11.3°至 0°）以及胸椎内背部弯曲（-15.2°至 0°）。此外，>90%的“带式活动”（日常工作的 46%）是站立进行的。
输送带活动的特点是躯干过度伸展的趋势，这可能是由于工作环境过高所致。此外，可以得出结论，站立时身体结构的负担增加。从初级预防的角度来看，应通过行为和关系预防措施来减少这种增加的站立负荷。
